the enlarged detail view, Fig. 3). The wireholding sides of the frame and the bar 9 are preferably of greater height than the frame ends. The top face of this bar 9 has a plurality of recesses 10, one for each of the wires 6. These recesses or grooves are of such depth that substantially one-half of the circumference of each of the wires 6 is received therein. Such provision is made in order that the grid wires may be suitably retained in alinement in such manner that the material may flatly lie upon the grid. The ends of this bar 9 are preferably provided with T-heads of width of the frame ends and are retained in the ends of the grid frame 7 by means of the screws 12. 1

In the disclosure shown in the accompany ing drawings,.a lever system is provided in order that the grid may easily be raised from a position submersed in the adhesive.

This system is preferably operable by means of .a pedal adjacent the floor. Provision is also made for adjustment of the lever sys tem so that greater or less force or travel of the grid movement may be obtained. In this embodiment, the grid frame 7 is provided with a pair of opposed cars 13 which upwardly project from the grid frame sides. While any suitable means may be employed to raise the grid, a pair of trunnions 14 is provided, one each being borne by an opposed ear 13. The inner end of each of the two trunnions 11 is inserted in an aperture 15 of each ear 13 and retained therein by means of the nuts 16. The outer end of each of the two trunnions is received and retained within an aperture in each block 17, terminally carried by the guiding rods 18. These rods 18 are reciprocally mounted in a bearing 19 secured to the support as by screws 20. These trunnions are engaged by the arms 21 of the lifting carriage of the lever system. The opposed grid ends of the arms 21 are preferably notched, as shown in dotted lines in Fig. 1. This construction affords a simple meansfor engaging the trunnions 14 in such manner that the grid may easily and expeditiously be demounted for cleansing, repair, replacement, or other purposes.- The trunnion-engaging arms 21 are pivotally mounted on the table 1 by means of a pair of brackets 22 supported thereupon and secured thereto by the screws 23. The opposite ends of the lever arms 21 are joined by a transverse bar 24 which in turn has pivotally secured thereto the upper end of the lifting rod 25. Reciprocatory movement is imparted to this rod by means of the lever member 26 which is pivotally mounted in the bracket 27 secured to the undersideof the table. This member 26 is similarly pivotally secured r both to the rod 2?, and, at its opposite end,

to one of the adjustment rods 28, the other adjustment rod 29 is pivotally secured to one end of a pedal lever 30. This lever is pivotally mounted in the bracket 31 positioned upon the floor and is provided with a' pedal Vertical adjustment of the effective lengths ofthe rods 28 and 29 is attained by means of the clamp coupling member 33; while, provision is also made for the variation of the application of the reciprocatory movement of the rod 28 to the transverse lever member 20. The latter is accomplished very simply by the provision of a plurality of apertures 31, each of which is adapted to receive the pivot pin of the block carried by the upper end of the rod 28.

In operation this mechanism is simple, rapid and easy to function. The reservoir is first filled with the adhesive substance desired to be employed. The level of the adhesive is preferably slightly above the level of the wires 6 of the grid when in its lowest position so that it thus covers the tops of the wires. When the pedal 32 is depressed, the lever 20 is rocked about its bracketed pivot which in turn entails the corresponding movement of the arms 21 of the lifting carriage. The trunnion ends of these arms effect the raising of the grid, guided by its rods 18 in the bearing 19. The grid in emerged position, as shown in dotted lines in Fig. 1, has its wi res clear of the liquid in the reservoir and presented for the facile emplacement of a piece of sheet material thereupon. As portions of the adhesive are left upon the upper faces of each of the grid wires, the simple positioning of a sheet object upon the grid causes the adhesive to be transferred to the object in a plurality of lines corresponding to the lines of the grid wires. After the object is thus treated, it may be removed and the pedal released whence the grid returns to submerged position. The grid is very easily removed by simply upwardly lifting the grid so that the rods 18 are free from their bearings, the ad justability of the leverage is adequate in range and effective in function while the working parts are few, positive in their action and of relatively low production and maintenance costs.

It is to be understood that the construction disclosed herein is illustrative but not restrictive and that the same may be modified within the meaning and scope of the claims which follow.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a machine for applying an adhesive, a support therefor; a reservoir for the adhesive; an instrumentality adapted to hear an adhesive comprising a frame, a plurality of members arranged in spaced relation, said members having their respective ends a support therefor;

and out of secured to the frame, means extending transversely 0f the frame and secured thereto means onsaid transverse means to engage said members to reinforce and to; retain them in said spaced relation; and means for reciprocating said instrumentality into and out of submersed position in the adhesive.

2. In a machine for applying an adhesive,

a reservoir for the adhesive; a grid comprising a frame, aplurality of grid-forming members arranged in substantial parallelism and having their respective ends secured to the frame sides, an instrumentality arranged transversely of the grid-forming members, means on said instrumentality to engage each of said grid forming members whereby said members are reinforced, and retained in spaced relation; and means for reciprocating the grid into submersed position in the adhesive.

3. In a machine for applying an adhesive, a support therefor; a reservoir for the adhesive; a grid comprising a frame, a plurality of grid-forming members arranged in substantial parallelism and having their respective ends secured to the frame sides, a bar arranged transversely of the grid-forming members and secured to the frame, a

plurality each engaging agrid-forming member to reinforce and retain the same in proper spaced relation, said instrumentalities engaging each member whereby the upper portion thereof is free to effect its adhesivebearing function; and means for reciprocat ing the grid into and out of submersed position in the adhesive.

4. In a machine for applying an adhesive, a support therefor; a reservoir for the adhesive; a grid comprising a frame, wires arranged in substantial parallelism and having their respective ends. secured to the frame sides and a bar extending transversely-of the wires and secured to the frame, said bar having a plurality of recesses on its upper face to engage a portion of all the wires whereby the upper portion of each Wire is free to effect its adhesive-bearing function and whereby the wires are reinforced and retained in proper spaced relation; and means for reciprocating the wired grid into and out of submersed position in the adhesive.

In testimony whereof, I have signed my name to this specification.
